Well, I was suddenly hit by inspiration, so I decided to post it and see what everybody thinks. Here goes:
Corrupticus, legendary titan of corruption.Model:

Standard titan stats, etc, I don't think I need to post them.
Abilities:
(I'll put icons for all the spells later, when I have more time)
Orb effect: Corrupting strike;
Corrupticus blights any enemies he may strike, causing them suffering and misery.
Any unit attacked by Corrupticus suffers 10 damage per second for three seconds. (innate)
Nuke: Corrupt life;
Corrupticus blights the ground around him, damaging all life nearby.
700 range AoE nuke damaging any units in the AoE for X. Costs Y mana. Also causes trees to look blighted (no effect other than for aesthetic purposes.)
Rank 1: X = 100 Y = 200
Rank 2: X = 130 Y = 250
Rank 3: X = 160 Y = 300
Heal: Corrupted rejuvenation;
Corrupticus utilizes what little healing power he has to rejuvenate himself, however, having servants nearby amplifies his little power in healing.
Corrupticus heals himself for X plus 150 more for each minion within 1000 range of him, and plus 50 more for each minion that has used its heal in the past 10 seconds.
Rank 1: X = 200
Rank 2: X = 400
Rank 3: X = 600
Rank 4: X = 800
Wind walk: Corrupt day;
Corrupticus causes the day itself to become corrupted, causing an unearthly night and hiding him.
By the way, if anybody could find a better image for this spell, such as like an eclipse or something, that would be greatly appreciated.
Corrupticus causes it to be night (similar to moon crystal) for 20 seconds, and be invisible except appearing briefly while attacking. (Basically, 20 second shadow catcher/satyryness) For X mana.
X = 150
Scout: Whispers in the forest;
Corrupticus has established his reign over nature in the island, and he can simply ask the trees themselves to find his enemies.
Ten random trees in the map give vision near themselves for a short time. Costs 250 mana.
(I can't think of a good ability for here, any suggestions?)
Ultimate: A pox upon you!
Corrupticus corrupts the builders themselves, causing them all to become ghouls slavishly attacking anything they see except corrupticus, their creator, and his minions.Corrupticus immediately makes all builders become Coruptlings. These will immediately attack the nearest builder structure or unit. The builders have no control over these. When killed, or after 10 seconds, they return to normal. If killed by corrupticus or a minion, the builder dies and spawns a minion as normal.

Wind walk: Steal the Night;
Corrupticus' minion sees that his master has had the need to cloak himself, so they, too, follow in his lead.When corrupticus uses his windwalk, "Corrupt Day," the minions sense danger and activate the same effect as Corrupticus (20 second shadow catcher)
Passive, innate.
Miniminis: Corrupted fleshling;
From the cadaver of one of the dead, corrupticus' minion spawns an unholy beast of tainted flesh.Standard minimini spell, simply a different model. Same minimini stats, 200hp, 20 dmg, etc etc etc.

Corrupticus' minion causes the enemies' towers to decay, causing them to be slowed for a time.Small AoE, slows towers in the AoE 50% attack speed. Does not stack.
FAQ (not really)
How do you play as corrupticus?Corrupticus is an early game leveling titan. He is not designed to be able to get minions easily, however, he requires them for late game base attacking. He is designed to be used in coherency with his minions, since many of their abilities do not work separate from each other, such as wind walk and heal. Once he has two high level minions and is high level himself, he can (should be able to) break bases with ease. His ultimate is designed to deal with pesky base supporters, and perhaps even get the main baser down. His and the minions ult is to minimize the damage output of towers, from slowing them and distracting others.
What's changed since the last time you've updated it?Minions and main's heal was completely remodeled, and damage over time of main titans innate was reduced. The damage over time was removed on the nuke.
What can I do?I need a better icon for his windwalk, shadowmeld just does not fit. Also, I need ideas for a unique ability.
What's coming next?More spell icons, a different unique ability, minion names, custom stats to make him even more unique, and him made in the world map.
I've heard news that you're going to change the name. What are your ideas so far?I've been playing island defense, and these are a couple of suggestions I've recieved: Blightious, Blighticus, corruptious, plagueritious. Tell me which ones you like, and suggest any others you think are good. I'll eventually post a poll for the name.
