Stupendous Man

Stupendous Man is Calvin's "superhero" alter-ego. He has used this form in the past, mainly to shift everyday odds in his favor (school, chores, etc.) and perform tasks that turn out to be pointless— for which he nearly always gets in trouble. Now, however, Calvin makes better use of Stupendous Man during battles in the "Dimension" saga, in order to give both himself and the team a better advantage; he does this by exploiting his flight capabilities, along with increased strength and speed.

FIGHT WITH FUTURE ALLIES
Stupendous Man first appears battling Mario, along with a group of other strange characters, over the seven chaos emeralds; he pursues Mario, and the two of them spin rapidly in midair, their capes striking each other all the while, until GIR flies in and separates them both. Caught by surprise from the sudden attack, Stupendous Man changes back to Calvin at this point, before later appearing again to ride on Hobbes' back while in midair, his flight and strength managing to sustain them both as they are pursued by Sonic and Tails. He and Hobbes plan an attack, and he throws Hobbes backward toward their opponents, just as the hedgehog shoots forward and blocks Hobbes' assault; Stupendous Man is then struck by Tails, but retaliates by punching him down to the ground below, and then flies forward and rams into Sonic, using his fist to deal a mighty blow that sends the hedgehog plummeting downward also. Just as he and Hobbes celebrate their victory, however, they notice the chaotic fight occuring in midair alongside them, and both are suddenly punched down to the ground by Luigi.

The battle soon comes to an abrupt halt as Sonic calls everyone to order; Stupendous Man changes back to Calvin, as the threat of Doctor Eggman is brought to the group's attention. When Sonic proposes that they all form an alliance to stop the Doctor, Calvin dons the cape and hood once more, to signify his new allegiance.

ATTACK ON MOBIUS
As the group is attacked by the Doctor's giant robot later on, Stupendous Man flies alongside Mario to perform the first counter-offensive; quickly dodging the ocular laser blasts and heat beams, they both strike the robot's face with powerful punches, knocking its colossal body over for a moment— but then the robot suddenly gets back up and rams into Stupendous Man with its head, blowing him backward. He shortly recovers from this, however, and later flies alongside the robot and allows Treeby to hop onto his back, the two of them dodging the robot's energy cannons all the while. As they land back on the ground, Tails flies in and collides with the "Spaceman Spiff" spacecraft that had crashed earlier. Stupendous Man asks Tails if he could fix the ship, and he then changes back to Calvin as Tails begins the repairs.

CESS POOL QUEST
Stupendous Man goes with half of the group to the Cess Pool in Zim's time period (dimension) to search for one of the now-missing chaos emeralds. After easily flying upward to the top of the wall, he dives straight into the pool to retrieve the red emerald— but momentarily forgets that Calvin cannot swim, and subsequently sinks into the depths, cape and hood coming off as he starts drowning. Calvin is eventually rescued by Knuckles and Luigi, and with the emerald reclaimed by Shadow, they all venture next to the Skool, Calvin inwardly deciding not to do such foolish acts anymore during this mission.

BOILER ROOM BROIL
Upon arriving at the Skool, Stupendous Man shows to everyone the new Emerald Radar he had created, and learns from it that the emerald they seek is inside the Boiler Room. He searches for said room along with everyone else, before it is later found by Yoshi; as they all enter, however, Egg Robos appear and ambush them, causing a fight to break out. Stupendous Man sees Luigi being chased by an Egg Robo, flies forward, and punches it away before it can shoot Luigi, as thanks for his rescue in the Cess Pool. The two of them continue to work together, fighting off several Egg Robos with more powerful hits, occasionally tossing one or two toward each other so that he may do the honors.

BRAWL AT BOULDER CANYON
Stupendous Man later appears for a short while during the group's battle against Swampy in Boulder Canyon. He and Hobbes attack the crocodile together, but Hobbes later tells him to run, sensing danger not for Stupendous Man, but for Calvin. Nevertheless, when a gigantic boulder suddenly begins tearing the canyon asunder as it rolls after everyone, Stupendous Man is able to use his flight capabilities to avoid the falling debris and quickly escape to safety along with everyone else.
