I’m finally back with another concept!
Sparky
Source: Lilo and Stitch
Description: Experiment 221, aka Sparky, is ready to wreak havoc on enemies with his massive electrical surges.
Quote: “Cuz-z-zin…”
Role: Damage
Position: Mid
Stars: 
Trial Team: Blue
Animations
Entrance: Sparky zips to his position.
Victory: Sparky cackles as electricity jolts around him.
Defeat: A glass vase falls on and traps Sparky, who zips around trying to escape, but to no avail.
Basic attack: Sparky zaps electricity at an enemy.
Skills
White - Power Surge (Fantastic Damage)
Passive: When Sparky lands a basic attack, he applies a stack of “Shock” to the enemy. Sparky deals 10% more damage to enemies per stack of “Shock” on them. Each enemy can have up to 10 stacks of “Shock”.
Active: Sparky zips through all enemies, consuming all stacks of “Shock” and dealing X damage to each enemy per stack of “Shock” on them and removing all of their active buffs. Sparky also heals himself for Y HP per stack of “Shock” on an enemy when he damages them.
Green - Lightning Blast (Fantastic Damage)
Sparky shoots blasts of lightning from his antennae at nearby enemies, dealing X damage to them as well as stealing 200 Energy from each of them and applying 3 stacks of “Shock” to each of them.
Blue - Electric Discharge (Fantastic Damage)
Sparky sends lightning to the enemy with the most Energy, dealing X damage to them and stealing 250 Energy from them. Sparky also deals X damage to enemies between him and the enemy with the most Energy with this skill and steals 100 Energy from each of them.
Purple - Quick Current
Sparky’s attack and movement speed are increased by 100% after using “Power Surge”. This buff is increased by 20% for each active buff Sparky removed from enemies while using “Power Surge”. The speed increase is less effective if the buffs are stolen from enemies above level X.
Red - High Voltage (Normal Damage)
While enemies are above 50% of their Max HP, they take X damage per second per stack of “Shock” on them.
Whenever Sparky or an ally steals Energy from an enemy, the enemy that they stole Energy from is stunned for 6 seconds.
+X Max HP
+X Basic Damage
+X damage dealt with “Power Surge” per stack of “Shock”
