This is my Iron Man concept that I submitted for the recent contest. Just wanted to post it in here, made a few changes. Also updated my R2 concept if anyone wants to give that a look again 
Iron Man: Marvel
Hero/Tech/Damage/Back/Red/3 Stars
•Biography: A backline damage hero that drains energy from enemies, and benefits from charged. Iron Man is one of Earth’s mightiest defenders. He’s the brains behind the Avengers, providing the team with various upgrades.
•Quote: “You can take away my house, all my tricks and toys. But one thing you can’t take away… I am Iron Man.”
Animations:
•Entrance: Iron Man flies on to the battlefield.
•Victory: Iron Man lands on the ground, removing his helmet and starts eating shawarma.
•Defeat: Iron Man’s reactor goes dark as he lands on the ground, falling to his knees.
•Basic Attack: Repulsor Beam (
)
Iron Man blasts an enemy with his repulsor beam, dealing X damage to them, and stealing X energy from them.
Attacks/Abilities:
•White Skill: Nanotech Canon ()
Iron Man releases his nanotech canon on the closest enemy, dealing X damage to them, and knocking them back, until he runs out of energy or KO’s them. On auto, he will only use this ability if he can KO an enemy.
Passive: Iron Man steals X energy from enemies with his basic attack.
(Leveling increases the damage of the skill. Stealing the energy with basic attacks has a chance to fail on enemies above level X)
•Green Skill: Nanite Manipulation ()
Iron Man can manipulate the nanites of his nanotech suit, allowing him to access an array of weaponry. He flies to the closest enemy, striking them with an energy blade, dealing X damage to them, and steals X energy from them. Then, he forms a shield with his nanoparticles, staying in melee range for Y seconds, and gains an X health shield on himself for the duration. During this time, Iron Man steals X energy from an enemy each time they damage his shield, and he attacks enemies with his shield. After, he flies back to his original position.
(Leveling increases the damage of the skill, and health of the shield. Stealing the energy has a chance to fail if the enemy is above level X)
•Blue Skill: Micro-Missiles ()
Iron Man unleashes a barrage of missiles at all enemies dealing X damage to them, and then studies them for Y seconds.
(Leveling increases the damage of the skill, and the study has a chance to fail on enemies above level X)
•Purple Skill: Maximum Power
While Iron Man’s energy is full, the power of his suit is increased, and he gains Charged on himself. When Charged, Iron Man gains X basic damage, X skill power, and heals for X health per second. Charged is dispelled when Iron Man falls below 1000 energy.
(Leveling increases the basic damage/skill power gained while charged, and increases the healing per second while charged)
