Sgt. Frog



 is this hilARious manga and anime series. It's about these group of aliens wanting to take over Pika-or something like that (And I'm not joking about the Pika thing. I'm serious.) or Earth as we know it. Kinda like Invader Zim but more hilarious with a LOT of pop culture references like Phineas and Ferb, but more heavy.

Characters
I feel like naming the five main aliens only. Is that alright?
 * Keroro - The leader and a brainless one.
 * Tamama - The mood swinging psychotic one.
 * Giroro - The serious yet distracted to some girl one.
 * Kururu - The brainiac but creepy one.
 * Dororo - The ninja and a peaceful one.
