A Taiwan-raised titanota selection with short, pale blue-white leaves and large white teeth. Its giveaway is the downward-pointing secondary teeth, larger than the main ones, a trait shared with 'Tarantula' and 'Demon Dragon'.

A titanota selection with large leaves bearing long, white, writhing teeth, sometimes called the finest of the named selections. 'Akuma-kun', 'Bakemono' and 'Super Titanota' are names for the same plant.

A compact titanota with thick, pale bluish-grey leaves and near-black teeth, selected by Kelly Griffin in the US from seed collected in Oaxaca. Often abbreviated to 'B&B'.

A titanota selection with broad leaves, moderately narrow tooth bands and a long, sharp tip spine: leaf width close to Juggernaut, with a more aggressive silhouette.

A Taiwan-raised titanota selection with short, thick leaves in a rounded rosette. Often mistaken for Hakugei with wet, darkened spines, but its form marks it as a separate line, closer to 'Azarashi' or 'Black and Blue'.

A titanota selection with broad, short, bright blue-grey leaves packed into a ball and many long, pure-white teeth that twist wildly. The waviness shows even on two-leaf pups.

One of the named titanota selections, sold as 'Godzilla'. Its traits and history are unclear, and plants under the name can differ, so judge teeth and leaf shape on the actual plant.

A Taiwan-born titanota selection with an exceptionally long, glossy black, wavering tip spine and brown teeth that give it a sinister look. Also sold under the Chinese name 黒帝斯.

A classic titanota selection: grown hard in strong light, short, rounded blue-grey leaves form a ball, edged with a thin white margin and small wavy teeth. Old Japanese stock and Taiwanese/Chinese imports both exist.

The name suggests a dwarf form of 'Ganryu', but in practice it is a loose trade name for small titanota types in general. Also called 'titanota dwarf', and plants vary widely.

A titanota selection with broad leaves and brown teeth. The name ('jewel') is said to refer to its ball-like habit, and it resembles Hakugei. Probably Taiwanese, but its history is unknown.

A titanota selection whose pale blue-white leaves broaden with age and develop deeply cut, wild teeth. Its spreading, slightly drooping habit is likened to a lion's mane.

A titanota selection that forms a round, compact ball set with large, devilishly wavy teeth. The contrast between the small, dense plant and its bold teeth makes it easy to spot among named selections.

A Taiwan-raised titanota selection with broad, blue-grey leaves. Its teeth are modest, so it reads as cool and composed rather than fierce. Also sold as 'Panda'.

A titanota cultivar that turns reddish all over in strong sun, making its rugged, wavy teeth stand out. Known in Japan as 'Akaneko' (red cat); it reverts to green in weak light.

A very compact titanota selection with broad white teeth, said to stay around 15 cm across even when mature, with a finely crafted look. Read 'Seiou'; also written with a simplified character.

A titanota selection that combines the bold shape of the green 'Sierra' type with whitish blue-grey leaves like the 'Rancho' type. Next to Hakugei its paler body is obvious.

One of the most iconic locality forms circulated under the name Titanota, described in 2019 as the new species Agave oteroi. The name derives from Felipe Otero's collection number. Dense white teeth and compact form make it highly popular. Selected specimens command premium prices.
