I'm annoyed that Shisami had such a shitty showing in Super. I feel like the character was capable of more than he was allowed to show.
Seems a bit odd that Sorbet was convinced Shisami was the strongest in Freeza's army when he specifically handpicked Tagoma to train with Freeza. If anything, you'd think training with Freeza alone would eventually make Tagoma the most powerful one. It definitely makes sense for Shisami to have training for those 4 months, though.
