SOLVED - A friend of mine helped me found out the title! It's Kutlas, I suggest anyone interested to watch it. Definitely worth the time.

I used to watch this cartoon series when I was very little (I'm 19, I probably watched it in the early 2000s). I can't remember much but I'll write down whatever I can.

• I first saw the show in the early 2000s.
• The protagonist was a semi-stickfigure man, completely colored in white.
• He had a girlfriend/fiance/wife, who's name was M or Maria and had an M shaped body.
• The setting and the story was overall very dark and mature for a cartoon (at least as far as I remember) with themes such as nuclear apocalypse, loss of loved ones etc.
• The language was English.
• I am not sure of the country of origin.
• I remember a radioactive apocalypse in which the protagonist (who might be a scientist/vigilante) seeks shelter in an underground vault/lab.
• I remember the specific quote "The shelter needs to be at least a hundred Kilometers under the ground to withstand a nuclear attack."
• I remember giant red ants inhabited the surface after the event, the protagonist mentioned radioactive fallout to be the cause of their drastic size change.
• A supercomputer type character kidnapped/murdered(?) the protagonist's girlfriend.

I'd love to be able to watch this show again! Please respond if you got a clue!
