Comparison canonical LRDs with the nuclear SEDs for several relatively low-redshift LRD analogs (at rest-frame wavelengths). The heavy solid lines show (1) the average SED from P. G. Pérez-González et al. (2024); and (2) the reddest example from the same paper, JADES-57356. WISEA J123635.56+621424.2 (i.e., the Saguaro discussed throughout this paper) is the heavy dashed line (the AGN portion only). The others are BiRD from F. Loiacono et al. (2025), GN-280754 I. Juodžbalis et al. (2024); RUBIES-BLAGN-1 from B. Wang et al. (2025c); WISE J101326.25+611221.1, a particularly luminous blue DOG identified by Y. Toba et al. (2018); JADES 191056 G. Barro et al. (2024a); WISE J125327.50+254747 G. Li et al. (2025); and J1025+1402 from X. Lin et al. (2026a).
