All the ways to counter bp:

Starting from least effort required to most effort required:

1. Play Elsa dino team up and stand afk with your supports and shoot him.

2. Play Angela starlord team up to ground him and kill him.

3. Play dd and just straight up kill him

4. Play Thing and earthbound him

5. Play triple support

6. Play triple support Ultron if you are still dying to that fuck ass character

7. Play any character with good mobility and mark him.

List of tanks that can successfully mark bp: Angela, Hulk, Tankpool, Venom, cap, thor, Rogue

List of dps that can successfully mark bp: starlord, daredevil, Elsa, Bucky, Black cat, spiderman, torch, iron man, Psylocke, iron fist, Dpspool, Elsa, Bucky, Mr F, (Do Note: there is a high chance you will 1v1 BP on these characters and your room for error is much higher which is why your tanks should be contest him first.)

10. Outheal his damage and or use support team ups that prevent him from playing the game. I dont play support so idk which team ups do what.

It is a failure for bp to even get to your backline.
