Solus (from Spider-Verse) has become Serpenta's new Miniboss, thus making Earth-001 a part of Serpenta's empire of 1,000,000,000+ universes. On an unrelated note, Hiro Hamada has modified his Heat Blazer armor, it now has a cape.
The next vessel of an Infinity Gem power, namely the Mind Gem, has been located in Earth Dimension EBMC25 (AKA the "Elf: Buddy's Musical Christmas" universe). The Big Hero 6 Unlimited then head over to that universe before the Axis of Evil does. Dr. Linksano uses a tracking device to locate the Time Gem power's energy readings. That energy reading was tracked dow to none other than Jovie. Jovie is kidnapped by the Weasels/Toon Patrol, who also have Infinity energy tracking devices and have had their van altered with interdimensional travel technology. After one epic battle against the Axis of Evil, our heroes have rescued Jovie, but the victory is bittersweet as the Time Gem energy has been sucked out of her. That's two Infinity powers down, three to go. To be continued...
