Lupin III: Part II, Space Cobra Recommendations
Both Cobra and Lupin both share an identical personality (silly, playful, clever, smart, and serious when they have to be). Most episodes from Space Adventure Cobra are episodic or are a 3-5 episode arc (although almost all he does is fight space pirates), but its mostly none-linear as is with Lupin III who also does the whole, "one mission an episode" thing with small arcs here and there.
While the setting and plot are different between the two series... Both series are quite similar in tone. The characters feel like they're written very similarly. Both Lupin and Cobra share many personality traits, and the antagonists in both series feel like they're written similarly as well. The art is pretty similar, too, with both series featuring detailed hand-painted CELs, and lots of expressive motion lines during fast-paced chase scenes. Even the soundtrack for both series are reminiscent of each other, featuring a lot of the same 70s disco undertones, and similar sounding stings and audio cues. If you like one, I would find it
