Badass Grandpa / Web Comics

  • The Beast LegionMaster Surya unleashes a powerful Ice spell to stop Xeus's Beast form.
  • Charby the Vampirate — Victor's grandfather John Marlowe is an incredibly skilled and knowledgeable Hunter of Monsters.
  • MAG ISA — Fr. Jose fits this trope. He can beatup a guy half his age.
  • Feng from Sluggy Freelance is supposed to be one of these, but his combat skills remain an Informed Ability.
    • Until he fights Kusari on even terms.
  • Thaco from Goblins.
  • Sa Paecheon from Gosu qualifies. Having once been renowned as the strongest martial artist of the old murim, he lost little of his fearsome strength in his old age, being the first and only person so far to fight Gang Ryong on equal standing throughout.
    • The old men of the Paelim Hall, the embittered group that served Sa Paecheon, also count, being made up entirely of former faction leaders whose factions were slaughtered by Sa Paecheon.
  • Old Man-Man from Dresden Codak.
  • Clark from Shape Quest, who is a wizard.
  • Ten Winds, from Keychain of Creation.
  • Raven in a more recent story arc in El Goonish Shive.
  • Girl Genius: The Foglios are pretty fond of this trope. In part this is because it's a World of Badass, and any serious contender who isn't dead yet is obviously not to be crossed.
    • Klaus Wulfenbach - the Big Bad(?) of the series - is actually a prematurely aged father, but has the two qualities of (a) looking elderly and (b) dominating every other mad scientist in Europe with an iron fist.
    • Dr. Sun, not just for his ability to make Bangladesh Dupree sit down and be good, or his willingness to tear apart a twenty-five foot mech with his bare hands, but for the expression of relief Klaus gets when their disagreement over the definition of bed rest does not end in a confrontation. Until it does.
    • Ol' Man Death qualifies as this and as a (semi-)Retired Badass. The guy 'rode with the Jaegers' in his youth, is referred to by Maxim as the greatest warrior ever, and despite his advanced age can toss a Jaeger (Maxim again) through a window without breaking a sweat. Keep in mind that Jaegers are immortal Super Soldiers who have been known to fight small armies by themselves.
      Ol' Man Death: No. Listen to me. I'm just a human. Rode with the Jaegers. Never. Lost. A . Fight.
    • Although Airman Higgs is quite a mystery, he is astoundingly capable once he drops his masquerade, and an increasing number of hints suggest that he is very old indeed.
  • Jade's Grandpa was this in Homestuck before he died which didn't happen yet as far as the Timeless Expanse in which many of the events take place is concerned.
    • His introduction (alive, anyway) involves him blowing up a butterfly with an old timey hunting rifle the size of a cannon.
  • Soul Symphony: Although physically a normal old man in real life, in Eric's Soul World his deceased grandfather is a dark, evil monster who fights in a shadowy suit complete with fedora and cane.
  • Discussed in this page of Real Life Comics.
    Do not underestimate the power of old-fu.
  • Remus gives us Marcus Laurent, a gruff, Two-Faced CIA agent who's part of Williams's grab squad.
  • From Schlock Mercenary is (retired) General Karl Tagon, who took on a squad of mob enforcers in the buff with nothing but a show-piece carbine and inflicted heavy casualties before they managed to stick his severed head in a jar. And he still managed to escape.
  • Commander Heroic in Evil, Inc. still fights crime when not in the hospital.
  • White Noise is one in Last Res0rt, who functions as the Captain of the Executioners (and thus, the other players on the show).
  • MS Paint Masterpieces: Dr. Light. He has giant robots and isn't afraid to take on a Robot Master.
  • In The Inexplicable Adventures of Bob! Nemesites are an alien race with a lifespan of about 2,000 years. Fructose Riboflavin is 1,900, and looks it, being incredibly frail-looking and haggard. He can still outmaneuver and disable a hulking guard robot and make it look easy... and then complain that his back hurts, but that's okay.
  • Dragon Ball Multiverse: Krillin (or "Kulilin" as the author insists on calling him), of all people. He seems to have mellowed out in his old age.
