Aliasing dengeki_pikachu -> dengeki!_pikachu.
Reason: I'd rather've waited out for more posts, but I'm hoping the non-letter/number aspect would warrant an alias now.
If so, then there's also...
electric_tale_of_pikachu
the_electric_tale_of_pikachu
pokemon_the_electric_tale_of_pikachu
pokemon:_the_electric_tale_of_pikachu
...to be wholly comprehensive on possible aliases.
