So a few days ago I tested some things out with all the different characters including the amount of time characters have rage, the amount of time characters can super block with a full super meter and how long characters can sprint, fly, teleport, swing or wall climb. This could be helpful for speedrunners but also for just playing the game casually

RAGE TIME (To the nearest half second)
23 seconds - Thing
22.5 seconds - Wolverine, Fault Zone
22 seconds - Elektra
21.5 seconds - Wink, Daredevil
17.5 seconds - Venom
17 seconds - Storm, Magneto
16.5 seconds - Spider-Man
16 seconds - Johnny Ohm
12.5 seconds - Solara, Brigade, Hazmat
12 seconds - Human Torch
11.5 seconds - Paragon, Niles Van Roekel
11 seconds - Iron Man

SUPER BLOCK TIME
6s - Wolverine, Wink, Elektra, Daredevil
4.3s - The Thing, Spider-Man, Solara
3.6s - Johnny Ohm, Storm, Fault Zone, Venom, Human Torch, Magneto, Hazmat, Paragon
2.9s - Brigade, Niles Van Roekel
2.7s - Iron Man

It appears lower tier characters with no projectiles, lower strength and/or less mobility have longer rages and can use the super block for longer as compensation.

Here is how long each character can sprint/teleport/fly/swing/wall climb with a full super meter

SPRINT TIME (Incl. wall running)
Thing - 12s
Wolverine - 28s
Elektra - 28s
Daredevil - 28s
Fault Zone - 28s
Brigade - 28s
Hazmat - 28s

TELEPORT TIME
Wink - 19s
Paragon - 48s
- Both characters can use their dodge alternatively to teleport without using any of their super meter

FLYING TIME
All flying characters can hover for 1 minute 7 seconds with a full super meter. Ascending quickly can deplete your super in just 7 seconds.

WALL CLIMBING
All wall climbing characters can wall climb for 1:35

SWINGING TIME
Daredevil - 0:44
Hazmat - 0:48
Spider-Man - 1:20
(Venom can only swing for a few seconds at a time because he loses height with each swing. Spider-Man also loses some height but slower)

It takes 5 minutes 30 seconds for Wolverine to regenerate his entire health bar. Wolverine's regeneration pauses whenever his claws are out. So basically if you're doing any super moves or holding down the right trigger, his healing will stop

I've also been thinking of doing tutorials on a bunch of characters outlining their move sets, the various pros and cons of each character, and how I'd recommend playing as them

So for Magneto, I've discovered a new pretty broken mechanic for Magneto. When you play against Magneto, the AI also uses this mechanic against you. After super grabbing items from a far distance, you can press the attack button to throw them before they reach you, allowing you to do severe damage to opponents quickly. This is useful in not just versus but also in Magneto's missions (Master of Magnetism and Death Incarnate).

It could also help with the fast kill strat in Poisoned Steel if you opt for that strat over the ring out manipulation strat

I've never noticed this. Very interesting!

Should try it for yourself if you haven't already. It makes Magneto a much better character to play as
