Krom also one of the few Space Wolves to deviate of the usual wolfing to the wolf degree, with a dragon theme for himself and his company.
One day Lukas the Trickster bet Krom that he couldn't outstare the sun. Never one to shy away from a challenge, Krom took the bet and spent a full day staring into the sun, going blind in one eye in the process. He ultimately called it a draw when the sun set.
While looking for the missing Logan Grimnar, Krom was captured by Dark Eldar. He fought in the arenas of Comorragh, managing to kill a Talos while his armor was unpowered and he had no weapon, not to mention that he was drugged out of his mind by the pesky xenos. He wound up working with a couple Dark Angels to escape.
Long story short, Krom felt sidelined and decided to hunt down Grukk Face-Rippa with only a small task force of Drakeslayers. This was a complete disaster. He didn't kill the warboss, but got his own ass kicked. Naturally, Logan Grimnar called him out on his stupidity. Later on in the battle, Krom led the Imperial forces, but only after most of the fighting was done. This embarrassed the shit out of Krom, and highlighted his unreliability.
Wrath of Magnus
While mostly in the background during this one, Krom did volunteer for inglorious guard duty as part of atoning for the above-mentioned mess. He also managed to help out the Grey Knights and contributed to proving the loyalty of the Wolves.
He's mostly a bog-standard Wolf Lord with a Master-Crafted Frost Axe (with build-in Shred USR). He does have a few tricks up his sleeve, like re-rolling failed saves near objectives and giving all Wolves in his Greatpack Furious Charge. He is rather squishly (3+ save, no EW etc.), but can stand his ground against majority of the characters (if they dont have str 8 or more).
