Ludwig Von Drake
“Hello, ‘dere’! Professor Ludwig Von Drake here. Certified scientist, and all-around expert on brilliant things!”
The great genius duck Ludwig Von Drake uses his intelligence and inventions to help out in the fight.
Stars: 
Role: Control
Position: Middle
Trial Team: Red
Entrance: Teleports into the battlefield with a teleporting Bathtub.
Victory: Thinks of a great idea as a lightbulb shines above his head
Defeat: Tries to throw an explosion potion but it explodes in his face
Attack: Shoots from his Ray gun
White Skill: Robotic Copies (Normal Damage)
Ludwig Von Drake summons robotic copies of Mickey and his friends to ride through enemies, dealing X damage and studying them or extending their current study for 3 seconds per robot. If the enemy is already studied, they take X damage over 12 seconds.
The first time he uses this skill, he summons one robot and summons one more each time he uses this skill. Ludwig can summon up to 5 copies and carries this between waves of a fight.
Green Skill: Explosion Formula (Normal Damage)
Ludwig pours liquid in beaker into another one, he puts a cap on it, shakes it, and throws into the fray, dealing X damage to enemies in an area, and stunning them for 6 seconds. If enemies are studied, they also have their attack and movement speed reduced by 50% for 12 seconds.
Blue Skill: Clever Calculations
Ludwig calculates the probabilities, studying all enemies for 10 seconds and granting himself 300 energy. If enemies are already studied, they lose X armor.
Purple Skill: Genius Inventor
Ludwig gains X skill power for each study on the battlefield. This includes studies on allies.
Red Skill: Study Strength
If an enemy blocks a study they receive 3 stacks of “Penalty”. Enemies deal 10% less damage with each stack of “Penalty” that they have, up to 6 stacks.
Allies deal 100% more damage to studied enemies and ignore 50% of their armor.
This effect is reduced against enemies above level X.
