Grinder-tron is Dr. Buttocks' evil doppelganger of Grinder who was made to help Betrayus take over Pac-World but was stopped by Pac and his friends.
Pac-Man and the Ghostly Adventures[]
Grinder-tron first appears in That Smarts! to help Betrayus take over Pac-World but fails due to being unfamiliar with the structure of the buildings in Pacopolis and getting drilled into the Netherworld by Pac.
Pac-Man and the Ghostly Adventures 2[]
Grinder-tron reappears in Pac-Man and the Ghostly Adventures 2 as the boss of Pacopolis and fights PacZilla.
Grinder-tron's attacks are as followed:
- Pulling PacZilla to him with his fan. PacZilla must brace himself in order to not get pulled.
- Spitting out missiles. PacZilla must eat up to three missiles to not get damaged and fight back against Grinder-tron.
- Grinder-tron can simultaneously spit out the missiles and pull PacZilla in.
- Throwing his fan along the ground. PacZilla must jump over the fan.
After taking enough damage, Cylindria will show up and fight for PacZilla and does so by attacking his arms and eventually his heart.
Grinder-tron's attacks in this phase are as followed:
- Firing two lasers out of his eyes. Cyli must dodge the lasers.
- Firing three missiles at Cyli. Cyli must also dodge the missiles.
- Attacking with his hammer arm twice. Cyli must dodge or attack the arm.
After attacking the heart enough, Grinder-Tron's head starts to uncontrollably spin which gives PacZilla the opportunity to repeatedly punch him into submission until he is finally defeated.
