Shank
Race For Victory
‘‘Road Warrior’’ now grants reality equal to 50% of armor boost.
‘‘Piston Slam’’ now steals all buffs. Cooldown of ‘‘Piston Slam’’ is reduced to 0 when Shank use ‘‘Final Lap’’.
Additional Stat Boosts:
Buff stealing have chance to fail against enemies above level X.
Here’s some more ideas.
Saving the day
“Stomp quake” reduces enemies basic damage by X for 8 seconds.
Whenever Mr Incredible damages an enemy with reduced basic damage while “Super duper” is active he stuns them for 5 seconds.
Stat increases:
The stun has a chance to fail against enemies above level X
Happy thoughts
Whenever an ally is healed while Joy has more than 5 stacks of happiness they gain X skill power by the end of the wave.
For every stack of happiness on Joy she gains 10% improved healing.
Stat increases:
Nighttime terror
“Shadow speed” has no limits and grants Darkwing 50% attack speed and 8 tenacity.
The cooldown for “Shadow stalker” is reduced by 1 second up to 5 seconds for every time an enemy has been stunned.
Stat increases:
That wouldn’t stack well with his Elastigirl disk.
Too short, any tenacity at all will be enough to ignore it.
NO.
Ehh. I’m not satisfied, I feel like there’s potential for something more creative.
That sounds pretty good, actually. 
Pretty much every other red skill gives hardy at this point, can’t the attack speed increase be higher instead? 
Why?
I added some changes:
“Saving the day” now reduces basic damage and stuns for longer
“Happy thoughts” grants skill power every time they are healing while Joy has more than a number of stacks of happiness.
“Nighttime terror” grants a higher attack speed buff and tenacity. I removed last part to it.
That’s better, sorry that I’m out of likes at the moment. 
I haven’t been keeping up, so if someone already did her, I apologize.
Judy Hopps
Red skill: Deputy Partner.
Judy Hopps’ deputize skill grants 300% more BD to the ally with the least basic damage (determined at the beginning of each wave.) and lasts 5 seconds longer. While this hero is on the battle field, Judy Hopps’ inspiration increases attack speed by 25% more, and also grants X Reality Shred.
Additional Boost.
+X Basic damage increase from Deputize skill
+X Max HP
+X Armor.
Megara
Greek Link
When Megara reaches 1 HP first time in battle she becomes invincible and diverts 80% of all damage taken by linked ally for 5 seconds.
Cooldown of ‘‘Self Sufficient’’ is reduced by 5% per each missing 10% HP on Megara.
‘‘Self Sufficient’’ now also heals a linked ally.
Increased diverted damage from linked ally has a chance to fail on ally above level X.
Additional Stat Boosts:
Miguel
Feel the Music
When Miguel removes a flat Note from enemies they take 15% of their max HP as bonus true damage.
Allies without healing notes are healed by the amount of 20% which healing Notes heal every 2 seconds.
Sharp Note from ‘‘Sharpen’’ is now given to all allies.
Bonus damage on enemies have a chance to fail against enemies above level X, and healing allies without notes is less effective on allies above level X.
Additional Stat Boosts:
+X HP
+X BD
+X SP to ‘‘Sharpen’’
Great. Love it!

“Self Sufficient” can remove 2 debuffs
Additioinal Stat Boosts:
Miguel
Music Mastery
He now targets 2 allies. there is 50% target 3 allies
“Healing note” has no limit
Additioinal Stat Boosts:
I know red skills cannot do animations, but can red skills steal beserk?
That would depend entirely on the skill itself. However, considering that only 2 heroes are able to go Berserk and one can’t even have it removed, I wouldn’t recommend it.
If it’s a passive effect added to another skill/a basic attack, yeah.
Just be careful not to make it too OP.
Altough rn we don’t have many berserk users so it’d be really situational
2 heroes? I thought it was only beast.
Davy is while his chest is alive. 
I guess it counts more or less
He literally has the berserk icon on him while the chest is in battle…
