Jhera's first reaction to this sight would be to scream and claw (or hoof) at the windows in an attempt to get out, but Power Surge's personality completely took over long ago. Power wielded his metal rod and seemed almost giddy with anticipation. He would have lunged at the pony (and the spider behind him) and began unleashing hell on both, but Jhera was still there. Although indirectly, he still had a voice in Power's actions. Glancing at the other passengers, he realized not all of them could fight. There was one cowering under a counter, possibly even crying. "Somepony, protect Spike!" Power yelled. "As for you, I would suggest getting that bleeding problem checked!" Power proclaimed as he advanced towards the poltergeist cautiously.
Ol' queenie over there has always and will always remind me of thr Mushroom pikmin that raped you in the first, and far more terrifying Pikmin.
