First edition Hideouts & Hoodlums had an explorer class for heroes like Kaanga, but there's really little reason not to use the fighter class for him, so far.
Also note that Kaanga only needs "a few weeks" to learn English, so picking up new languages is something heroes can do on their downtime.
I like the unusual Macguffin of magical healing stones.
White Panther is clearly a superhero (or maybe a speedster from 1st edition!). He activates Race the Train to outrun the natives, and it is interesting that he uses his power only as a distraction instead of trying to use it to fight anyone.
It's unclear from panel to panel if White Panther is a naked albino or wearing skintight white clothes from head to toe. He also seems to have a magnetic disc on his belt that holds his dagger in place, which is pretty cool.
Here's a reason not to carry guns in cave complexes -- gunshots apparently have a chance to cause cave-ins! Cave-ins are pretty brutal, delivering fatal damage for those who miss their saves vs. science, and tearing the clothes of even those who make their saves.
There are three crocodiles on the next page, so we know crocodiles can be encountered in groups of up to 3.
