We present the first high resolution He ii λ4686 images of the high excitation nebula around the WR star Brey2 in the LMC. This nebula presents a striking morphology: a small arc-like feature some 3.6 pc in radius is particularly prominent in the He ii λ4686 line. We further discover a previously unknown faint He ii emission that extends over an area of pc2. An even fainter He ii emission is apparently associated with the interstellar bubble blown by the progenitor of Brey2. The total He ii flux corresponds to an ionizing flux of photons s-1. Hα, [O iii], and He i λ5876 images and long-slit spectra are also examined in this letter, enabling us to investigate the detailed physical properties at various locations of the nebula.
