Power Punch II is a boxing video game developed by Beam Software for the Nintendo Entertainment System (NES) and originally released in North America in June 1992.

The game puts the player in the role of Mark Tyler, an undefeated heavyweight champion on Earth who is invited by an outerspace boxing federation to fight the toughest challengers in the universe.

Power Punch II was initially developed as a sequel to Nintendo's popular 1987 NES boxing title Mike Tyson's Punch-Out!!

[citation needed] Mark "Tough Guy" Tyler is the undefeated heavyweight champion of the world, with an Olympic gold medal and a 33-0 (30 KO) record to his claim.

!, Beam Software's project, originally titled Mike Tyson's Intergalactic Power Punch, was to star the eponymous boxer, this time as the player-controlled protagonist.

"[12] In 2009, a playable prototype ROM of Mike Tyson's Intergalactic Power Punch was released online by a collector after funds were raised from users of a popular Nintendo forum.

[9][11][13] Piko Interactive eventually acquired the rights to Power Punch II and in 2019 released the game digitally on Steam for PCs that use Microsoft Windows.

GamePro remarked that it had "slightly better than average 8-bit graphics and challenge" yet that the player's limited moveset lacked realism and that the game became repetitive once each opponent's weakness was found.

"[10] Charles P. Gill of Hardcore Gaming 101 criticized the graphics as being better suited for a 1986 release rather than one from 1992 and stated that the gameplay "walks a line between boring and massively frustrating".
