chimera

Bellerophon was commanded to destroy this monster, and with the assistance of the flying horse, Pegasus, he slew the chimera.

A voice had called him forth to think in solitude—a voice he durst not resist, the awful one of the future. It fell on John's heart like the mutter of approaching desolation. He heard it coming on, as the spell-bound in a hideous dream await, wordless and shivering, the progress of some chimera monster, whose grasp is to crush and destroy.

The car which he built himself was a real chimera: half Volkswagen and half Porsche.

The famous parapet chimeras on the north tower of Notre Dame in Paris, especially the brooding double-horned fellow with protruding tongue on the west parapet originally assumed to relate to a thirteenth-century model, are classic examples.

[P]reembryo cells from different parents can combine and grow into a chimera (an individual with cells from two or more zygotes)—in this case, an entity containing genetic material from four parents! Spontaneous chimeras […] occur rarely in our species. Recent examples include a woman who resulted from the merger of two zygotes or the early fusion of two genetically distinct embryos.

The chimeras […] are an extant group of about 30 species. They have the upper jaw fused with the cranium and a gill cover over the four gill slits. They also have toothy plates that give them a ratlike appearance, thus the common name "ratfish." The group occurs in ocean depths worldwide, where they mainly feed on invertebrates.
