He is also, as stated in his Japanese e-Card info, Poko's father. He is the only villager other than the female kangaroo villagers to be a parent, and the only male parent to be recognized in the game so far.
Ike is dark brown with golden markings around his eyes, possibly mimicking a sun bear. His eyes have large black pupils and are half-closed. His default facial expression resembles a frown, making him look tired or disinterested. He has a shiny, somewhat rectangular black nose. His paws, muzzle, and the insides of his ears are beige, with the color transitioning from brown to beige in a zigzag pattern. He wears a jungle-camo shirt in Animal Forest e+ and New Leaf, which changes to a camo bomber-style jacket in New Horizons.
Below is a brief description of the cranky personality. For more information, click here.
Cranky villagers will usually appear in a grouchy or agitated mood and are more difficult to befriend than most other villager types. When talking to the player, cranky villagers tend to become angry if the player disagrees with them or refuses to do a favor. Like all cranky villagers, Ike will be invested in his hobby and will often challenge the player to various competitions. He will easily get along with jock, snooty and other cranky villagers, and occasionally lazy and normal villagers as well. However, he will find it hard to socialize with peppy villagers, as they will seem overstimulated or immature. Ike will also enjoy spreading rumors about other villagers.
Ike's house in Animal Forest e+ has the same furniture styling as Kody's house, only that he has changed the wallpaper Ike has is the Cabin Wall and the Red Tile as the flooring in his house.
In New Horizons, Ike's house resembles a workshop or garage. In the back of his house, he has an iron shelf, DIY workbench, and ironwood DIY workbench with a wall-mounted tool board and studio wall spotlight above it. In the middle of his house, he has an iron worktable with a toolbox and portable radio on top of it, and a tool cart next to it that has a wooden toolbox. He also has a camping cot (camouflage), breaker, and key holder. For wallpaper, he uses the Shutter Wall, and for flooring, he uses the Steel Flooring.
His English name might be a reference to U.S. President Dwight D. Eisenhower, whose nickname was "Ike." Eisenhower signed the Smokey Bear Act as part of a national wildfire prevention campaign led by the character Smokey the Bear, who Ike resembles.
Ike shares his English name with another Nintendo character from the Fire Emblem series.
His Japanese name, "Daiku," can be read as "carpenter." Incidentally, his goal is to be a carpenter.
The profile of the Japanese version of the card e+ says "何よりも大切な息子、ポコ。(Poko, my most important son.)". He is the father of a Cub, Poko, who appears only in "AFe+".
