What a surprise, it’s Dai-Rukh! What’s more, he’s here with another wacky idea. Thanks so much for the comments and help with Psychosis. I really enjoyed, and am enjoying, working on him. But, I’m one of those people who can’t keep their ideas for Island Defense to themselves, so…
Biosis, Legendary Titan of Mutation Even after the Titans awoke from their sleep of 499 years, one remained dormant. It fed off of the life energy of the island, constantly changing, and it grew. It became more powerful than it, or its titanic brothers could have ever imagined. It was Biosis, the Titan of Mutation, and its power was fueled by the creatures of the island constantly changing to survive. But now, Biosis hunts… Biosis is a very difficult titan to play for one obvious reason: he has 2 forms, a Passive Form, and an Aggressive Form. Each has different powers, but it is necessary to use both to effectively play as Biosis.
Titan (Passive Form) 
(Possibly tinted brown or red)
Icon:

Base Hitpoints: 900
Base Mana: 300
Base Strength: 36 (+8)
Base Intelligence: 40 (+7)
Base Agility: 42 (+4)
Base Damage: 60 (Hero)
Speed: normal
Base Armour: -1 (Hero)
This is Biosis’ default form (he spawns as this). It has considerably less strength than a normal Titan, but has one more ability than his Aggressive Form.
Abilities: Aggressive Form
Biosis morphs his body, empowering him muscles and growing bones while diminishing his memory and intelligence. This power turns Biosis’ Passive Form into his Aggressive Form. 5 second casting time and a 30 second cooldown (begins after Biosis reassumes Passive Form). As you may have guessed, Biosis starts with this ability.
Clone Flesh
Biosis rapidly restores his body’s cells and tissue, speedily regaining strength. Unfortunately, this process can be interrupted. This is Biosis’ heal. Clone Flesh restores health over a period of time. If Biosis is hurt in this period, the heal stops. Biosis starts with Level 1 automatically when he spawns.
Amount Healed: 500/1000/1500/2000
Time Required: 10/15/20/25 seconds
Cost: 200/250/300/350 mana
Required Level: auto/3/5/7
Cooldown: 20/25/30/35 seconds.
As usual, Biosis’ Passive Form has a
Slow Poison/
Chameleonize
Biosis morphs his skin color, blending in perfectly with his surroundings. Only a keen eye can see him is this state. This is Biosis’ equivalent of a wind walk: his model gains 100% transparency for the duration and he can only be attacked if directly targeted (namely no auto-attacking, even from towers). If Biosis casts any spell in this state, Chameleonize immediately ends. However, he is allowed to attack while Chameleonized without the spell being lifted. Level 3 required. 60 second cooldown. 12 second duration. Thanks to Coaster_Man for the idea.
Speeded Cell Reproduction
In his Passive Form, Biosis can devoted more of his energy towards keeping himself alive. He can learn how to keep himself in a state of constant cell production inside of his body, regenerating himself quickly. This is a passive ability which grants Biosis +40% health regeneration while in his Passive Form. Requires level 6.
Tentacle Snatch
Biosis’ Passive Form is an amorphous blob, able to twist and contort itself, unlike his bony, muscled Aggressive Form. However, his flexible Passive body does allow him to grab at nearby foes, holding them in place as he strikes. Tentacle Snatch stuns a targeted unit for 2 seconds. However, it can only be used on enemies within 500. 180 mana, 30 second cooldown. Level 6 required.
Shrink (Ultimate)
As is known, Biosis’ Passive Form is very malleable. However, when he gains enough power, the Titan can actually shrink himself, sneaking through defenses to attack the builders behind them. Biosis becomes a 1x1 space, allowing him to slip between wall gaps and into sneaky spots. Biosis cannot cast any spells while shrunk, and he has only 25% of his normal health and cannot Attack. If Biosis returns to normal size in a spot he could not normally enter, he will enter the closest space that it is possible for him to fit in when Shrink ends. Shrink lasts for up to 10 seconds, but may be ended at any time.Level 10 required, 200 mana, 5 second casting delay, 60 second cooldown.
Titan (Aggressive Form) 
Icon:
Biosis’ Aggressive Form has the same stats as his Passive Form, EXCEPT it has 33% more strength at all times.
Abilities: Passive Form
Biosis, when he needs to heal or creep about, returns to his weaker Passive Form, returning his bones and muscles to a kind of biological glop. Biosis changes from his Aggressive Form to his Passive Form. This has a 5 second casting delay and a 30 second cooldown which begins when Biosis assumes Aggressive Form. Aggressive Form starts with this ability.
Biosis’ Aggressive Form also has a
Slow Poison.
Consume
Biosis stretches out his Aggressive Form’s long neck and takes a large bite out of anything nearby. Any creatures who cannot escape his enormous maw are eaten, and their flesh and bone becomes part of Biosis’ body. This is Biosis’ nuke. His Aggressive Form starts with Level 1 of this spell. Consume is quite powerful. All inside of the AoE take full damage, including Biosis himself or one of his Minions, if they are in the AoE.
Damage: 140/160/180
AoE: 250/275/300
Range: 450/500/550
Mana Cost: 240
Cooldown: 12 seconds
Required Level: auto/4/6
Unstable Mutation
Biosis uses his power to distort a targets body, giving them powers even Biosis can’t predict. This is a very much miscellaneous spell which Biosis casts on himself. Unstable Mutation has a 33% chance to either increase speed by 15%, armour by 5, or attack damage by 30% for 10 seconds. 150 mana, 60 second cooldown, Level 5 required.
Muscle Burst
Biosis superpowers himself, expanding his muscles, growing his arm-scythes, and transforming his body into a seriously dangerous killing machine. Biosis gains +25% Attack Speed and +25% Damage for 10 seconds. 250 mana, 60 second cooldown. Requires Level 7.
Division (Ultimate)
Biosis’ Aggressive Form undergoes mass mitosis, all of the cells in his entire body divide, and he splits himself into two. Biosis spawns an exact copy of himself. When he does this, however, he takes half of his health and the clone spawns with only half of its health. Only the original has inventory slots and can carry and use items, but both clones can fight and cast spells, though neither is allowed to return to Passive Form. If the original dies but the clone survives, the Aggressive Form is respawned with all of his items at the life the clone was at. This whole process works much like Storm, Earth and Fire. The spawned clone lasts for up to 15 seconds. 5 second casting delay, 500 mana, 120 second cooldown. Requires Level 10.
Minions 
Icon:

Base Hitpoints: 900
Base Mana: 200
Base Strength: 40
Base Intelligence: 30
Base Agility: 35
Speed: Normal
Base Damage: 60 (Hero)
Base Armour: -1 (Hero)
Names:
Swamp Thing
Worst Nightmare
The Blob
Mr. Fantastic
Tumor Incarnation
Pudding
Primordial Soup
Thing 1
Thing 2
Platypus Abilities: As per normal, Biosis’ minions have a normal
Slow Poison.
Needle Spray
Biosis’ Minions have many bizarre anomalies (an occupational hazard when you work for the Titan of Mutation), and many can learn how to launch deadly spikes out of their bodies in every direction. This is the Minions’ nuke, and it works exactly like the move Fan of Knives. Each level fires a varying amount of darts, each of which go a certain distance and do a certain amount of damage. 3 levels.
Damage per Needle: 100/150/180
Range: 500/600/650
Number of Needles: 6/8/12
Mana Cost: 300
Cooldown: 16 seconds
Required Level: 2/4/6
Ajoin
Biosis’ Minions can, quite literally, link with him. This link keeps Biosis alive, whilst transferring all serious injury to his followers. This is technically the Minions’ heal. It works like a spirit link which causes the Minion in question to take a percentage of the damage directed at Biosis. Ajoin is a channeling/leash spell: the Minion using it cannot perform any actions while doing so, and if the target leaves the spell’s range it ends. 4 levels.
Range: 500/600/700/700
Mana Cost: 200
Cooldown: 30 seconds
Damage Percentage Given to the Minion: 50%/66%/80%/100%
Required Level: 2/4/6/8
Chameleonize
Biosis’ Minions can also blend into their surroundings to an extent, though they are not close to as masterful at it as their Titan. This works exactly like Biosis’ wind walk, except that it only lasts 5 seconds. Otherwise it has the same stats as a normal Minion wind walk.
Experiment
Using a dead corpse, Biosis’ Minions can perform bizarre and often disgusting experiments, which can result in some strange creations. This is the Minion-Minion spell. Experiments behave exactly as normal Minion-Minions except that, when spawned, they have a 30% chance of being a flying unit and a 5% chance of being ranged (400). An Experiment CAN have both of these random occurrences. Otherwise, however, Experiments have the same exact stats as normal Minion-Minions, as does the Experiment spell. Flying Experiments, like Breezerious' Harpies, have no vision of their own, though normal Experiments do.
Experiment 
(Experiments are tinted slightly red if they are ranged, slighty blue if flying, and slightly purple if both.)
Tentacle Beast (Ultimate)
The Minion in question is overwhelmed by mutative energy and starts growing enormous tentacles out of its body, which smash nearby structures with obvious malice. When used, the Minion gains a highly unpleasant, tentacle-related power. Every second, a tentacle will come out of the Minion and smash a random structure within 400 for 25 damage. Costs 300 mana to use, lasts 20 seconds, and has a 240 second cooldown. Requires Level 8.
Here it is, the end of another Titan suggestion. Thanks for reading. I love advice, so please give me yours.
