Nope. In the bar fight in "Trouble With Tribbles" he did try to fight a Klingon. Of course, the Klingon easily tossed him across the room and into the far wall...Chekov. He'd hide in the corner while the other two beat the crap out of each other.
Seven would mop the floor with Worf, either in combat, sarcasm, singing, and dead-panning.Worf hands down. Seven was ok but she wouldn't be able to match Worfs skills in hand to hand combat nor would she be able to match his strength.
Major disagreement here. Worf was okay in small doses, but he got to be just way too much shoved in our faces, week after week, year after year, program after program... And at the end of the last TNG movie, was Worf's personality much changed from "Encounter at Farpoint"? Not much that I could see.Such an easy call, Worf, Son of Mogh. A character with full dimension, a force to be reckoned with and worked his way up from the back of the bridge.
I always liked Chekov, he had a lot of humor to him, he was easily one of my TOS Favs
Seven- Never in contention, She was well acted and is a beauty to be sure, but the character never grew at all. If there had been character growth, I probably would have been more interested in her. As she was, boring after 6 episodes. So much of the 2nd half of Voyager was wasted on her. Really, really sad.
Seven, on the other hand, changed considerably from her first introduction to "Endgame." The changes were subtle, but definite.
